Constructor Detail

SettingsModelLong

public SettingsModelLong(String configName,
                         long defaultValue)

Creates a new object holding a long value.

Parameters:

configName - the identifier the value is stored with in the NodeSettings object

defaultValue - the initial value

Method Detail

getNumberValueStr

String getNumberValueStr()

Specified by:

getNumberValueStr in class SettingsModelNumber

Returns:

a string representation of the current value

setLongValue

public void setLongValue(long value)

If the new value is different from the old value the listeners are notified.

Parameters:

value - the new value

getLongValue

public long getLongValue()

Returns:

the stored long value

setNumberValueStr

void setNumberValueStr(String newValueStr)

Sets a new value in this object. Parses the passed string. Throws an exception if the value is invalid.

Specified by:

setNumberValueStr in class SettingsModelNumber

Parameters:

newValueStr - the string representation of the new value to set.

getConfigName

protected String getConfigName()

Specified by:

getConfigName in class SettingsModel

Returns:

the name provided at settings model construction time. The id associated with the value.

createClone

protected SettingsModelLong createClone()

Specified by:

createClone in class SettingsModel

Returns:

a new instance of the same object with identical state and value(s).

getModelTypeID

protected String getModelTypeID()

Each settings model provides an ID which will be stored with its values. This is to ensure that the same type of model is used to read the values back. Otherwise an assertion will go off. Make sure to provide a unique ID - and to re-use that ID in all compatible models. IntegerModels for example should use the same ID as BoundedInteger models.

Specified by:

getModelTypeID in class SettingsModel

Returns:

a string that identifies all models that are able (and empowered) to read the values stored by this model.

loadSettingsForDialog

protected void loadSettingsForDialog(NodeSettingsRO settings,
                                     PortObjectSpec[] specs)
                              throws NotConfigurableException

Read the value(s) of this settings model from configuration object. If the value is not stored in the config, the objects value must remain unchanged. Called only from within the components using this model. If the model is disabled it should not throw the exception.
This method must always notify change listeners!!
NOTE: Do not call this method directly, rather call dlgLoadSettingsFrom

Specified by:

loadSettingsForDialog in class SettingsModel

Parameters:

settings - The NodeSettings to read from.

specs - The input specs.

Throws:

NotConfigurableException - if the specs are not good enough to

loadSettingsForModel

protected void loadSettingsForModel(NodeSettingsRO settings)
                             throws InvalidSettingsException

Read value(s) of this settings model from the configuration object. If the value is not stored in the config, an exception will be thrown.
NOTE: Don't call this method directly, rather call loadSettingsFrom.

Specified by:

loadSettingsForModel in class SettingsModel

Parameters:

settings - The NodeSettings to read from.

Throws:

InvalidSettingsException - if load fails.

saveSettingsForDialog

protected void saveSettingsForDialog(NodeSettingsWO settings)
                              throws InvalidSettingsException

Write value(s) of this component model to configuration object. Called only from within the components using this model.
NOTE: Don't call this method directly, rather use dlgSaveSettingsTo.

Specified by:

saveSettingsForDialog in class SettingsModel

Parameters:

settings - The NodeSettings to read from.

Throws:

InvalidSettingsException - if the user has entered wrong values.

saveSettingsForModel

protected void saveSettingsForModel(NodeSettingsWO settings)

Write value(s) of this settings model to configuration object.
NOTE: Don't call this method directly, rather call saveSettingsTo.

Specified by:

saveSettingsForModel in class SettingsModel

Parameters:

settings - The NodeSettings to write into.

toString

public String toString()

Derived classes should print their class name plus the config name for nice and useful error messages. Like that,
return getClass().getSimpleName() + " ('" + m_configName + "')";

Specified by:

toString in class SettingsModel

validateSettingsForModel

protected void validateSettingsForModel(NodeSettingsRO settings)
                                 throws InvalidSettingsException

Read the expected values from the settings object, without assigning them to the internal variables! (Is not called when the model was disabled at the time the settings were saved.)

Specified by:

validateSettingsForModel in class SettingsModel

Parameters:

settings - the object to read the value(s) from

Throws:

InvalidSettingsException - if the value(s) in the settings object are invalid.

validateValue

protected void validateValue(long value)
                      throws InvalidSettingsException

Called during validateSettingsForModel(org.knime.core.node.NodeSettingsRO), can be overwritten by derived classes.

Parameters:

value - the value to validate

Throws:

InvalidSettingsException - if the value is not valid and should be rejected
